Inventor: ARCHER DAVID D
IPC: H04M1/21
Filed: 1991-01-17
Abstract: A telephone handset includes a light bulb and has a  special switch that  allows the light to automatically  illuminate  upon using  the phone.  The switch changes from an open position to  a closed one upon a change in its orientation relative the force of gravity.  One embodiment of the switch includes a hollow  chamber having  two  separate contact plates disposed at one  end  and a freely sliding conductive member that comes into contact with the contacts  upon picking up the phone.  A second switch  embodiment includes  three  parallel  pins with a central one  of  the  pins having  a hanging pivoting member that serves to contact  one  of the other pins upon a change in gravitational orientation.   Also included  is a removable socket member to facilitate  replacement of the bulb.

Title: Rapid-setting flowable backfill composition and method of using
Inventor: BENNETT BRUCE H
IPC: C04B28/02
Filed: 1991-04-26
Abstract: The subject invention relates to a rapid-setting self-hardening backfill composition and method of installation. The composition comprising a minor amount of Class C fly ash as a primary constituent and other filler materials such as Class F fly ash in major amount. When such materials are combined with water in controlled amount, they produce a backfilling material which is flowable and self-leveling for easy installation in utility trenches and similar excavations in street and roadway surfaces to support relatively heavy compressive loads within relatively short periods of time without settling. The self-hardening initially flowable mixtures attain considerable strength for withstanding traffic loads without undue settling in time periods of about 4 hours. The rapid-setting of the composition provides a rapidly attainable strength of the order of about 20 psi within about 4 hours to permit overlaying a wearing course of paving material and reopening of excavated areas of streets and roadways without undue traffic delays and congestion. The backfilling composition ranges in amount from about 2 to 10 parts by weight filler material to about 1 part by weight Class C fly ash with sufficient water to react with both Class C fly ash and filler material. The composition utilizes by-products of coal-fired power stations to form a most economical backfilling material and method of utilization to provide both early strength and precisely controlled permanent strength to permit ready reexcavation.

Title: Process for incorporating hologram into laminar structure with wet photograph
Inventor: MAILLOUX DENNIS R
IPC: B42D15/10
Filed: 1991-07-31
Abstract: A laminar structure, for example an identity card, comprises a photograph and a supported hologram.      A moisture-impermeable barrier layer and an adhesive layer are disposed between the hologram and the photograph, so that the photograph can be secured to the hologram while the former is still wet. The supported hologram, the barrier and adhesive layers and the photograph are sandwiched between first and second sheets. The hologram is sufficiently adhered to the photograph that, if an attempt is made to separate the supported hologram from the photograph, fracture will occur within the hologram or between the hologram and its support sheet, so that at least part of the hologram will remain attached to the photograph, so that it is not possible to detach the hologram from the photograph, leaving the hologram attached to the first sheet, and thus substitute a different photograph in the laminar structure.

Title: Process for preparing polycrystalline cubic boron nitride and resulting product
Inventor: CORRIGAN FRANCIS R
IPC: C04B35/5831
Filed: 1991-11-28
Abstract: PROCESS FOR PREPARING POLYCRYSTALLINE CUBIC BORON         NITRIDE AND RESULTING PRODUCT                      ABSTRACT OF THE DISCLOSURE       The present invention is directed to an HP/HT process for making polycrystalline CBN particles and compacts from graphitic boron nitride (GBN) (including PBN, HBN, and mixtures) in the substantial absence of bulk catalytically-active material. The inventive process modulates the HP/ET conditions of the process and comprises doping said GBN with between about 0.1 and 50 weight-% of non-BN atoms or elusters thereof, an amount thereof being incorporated into the CBN lattice for at least lowering the pressure required for making said polycrystalline CBN in the absence of said atoms or clusters thereof The plesence of non-BN atoms/clusters or foreign atoms is termed "doping" and should be contrasted to the formation of a "composite" as disclosed in commonly-assigned U.S.S.N. 367,299, filed June 16, 1989. Doping of GBN with foreign atoms in accordance with the present invention involves the atomic level dispersion of foreign atoms independent of concentration. Thus, for present purposes, it is the size of foreign atoms and their distribution that determines whether a doped GBN material for processing in accordance with the present invention has been made or whether a conventional composite has been made. A composite, it will be appreciated, refers to the bulk addition of foreign material to GBN. In this regard, it should be understood that the same percentage of foreignatoms may be defined as suitable for producing a "composite" conventionally, but that this definition refers to macroscopic (particle size) mixtures; whereas, the same percentage may be termed a "doped" mixture for present purposes if the foreign atoms are present in an atomic level dispersion of atoms or clusters thereof. The resulting CBN product forms yet another aspect of the present invention. Another technique for moderating the HP/HT conditions in forming the CBN comprising coforming GBN atoms or clusters thereof isolated from each other by non-GBN clusters or particles. For present purposes, "coforming" means that the GBN and non-GBN materials are formed in the stated physical relationship simultaneously or at the same time. Acceptable techniques for this coformation include, for example, chemical vapor deposition, solgel techniques, polymer pyrolysis, and combustion synthesis techniques.

Title: Porous membranes suitable for separation devices and other uses
Inventor: THOMAS MICHAEL PATRICK
IPC: B01D71/02
Filed: 1990-09-28
Abstract: Porous membranes incorporating porous anodic films are disclosed. The membranes, which may be used as filters, gaseous diffusion media, dialysis membranes, etc,, are produced by porous anodizing aluminum or other porous anodizable moral, creat-ing a weakened stratum in the resulting porous anodic film (e.g, by a voltage reduction procedure during the anodizing step), at-taching a support to the porous anodic film and separating the film along the weakened stratum. If the support is perforated the resulting structure is suitable as a separation device. If imperforate, the support can subsequently be perforated, if required, or re-placed by a perforate support or supporting structure. The resulting structure has a non-metallic imperforate or perforated sup-porting layer (made, for example of plastic or ceramic) or other supporting structure, reinforcing a porous anodic film in which the pores completely penetrate the film.

Title: Electronic torque wrench and overshoot compensation circuit therefor
Inventor: ANNIS JEFFREY R
IPC: G05D17/02
Filed: 1992-03-03
Abstract: Abstract of the Disclosure A torque wrench has a battery-powered sensing circuit which produces a torque signal proportional to the level of the torque applied.  A reference signal corresponding to a predetermined torque level is subtracted from the torque signal to produce a difference signal which is, in turn, compared with a compensation signal which is proportional to the rate of change of the torque signal and is produced by differentiating the torque signal.  When the value of the difference signal exceeds the value of the compensation signal, an indicator is triggered to produce a tactile indication, the indication being produced prior to the time that the torque signal reaches the reference level by a predetermined time period.
